Salivary cortisol as a marker for assessing the problem‐focused coping style of stressed students during the first year of university: An experimental study

Abstract

Background and Aims First‐year students encounter substantial stress when they enter university. Their mental health often depends upon how well they cope with the stress of university life. Salivary components are well known to reflect the stress status of the students; however, the relationship between salivary components and coping styles remains unknown. Methods In this study, 54 healthy first‐year students voluntarily completed a questionnaire that addressed three different coping styles: problem‐focused, emotion‐focused, and escape‐focused. We simultaneously collected salivary samples from students in the classroom and measured concentrations of salivary cortisol and α‐amylase by enzyme‐linked immunosorbent assays over 4 months. Results We examined the relationship between coping style and salivary cortisol concentrations and found that the mean salivary cortisol concentrations were significantly lower in students who had a higher Likert‐type score for the problem‐focused coping style than in students who had a lower score. The difference in the mean cortisol concentrations between the two groups increased over time. However, we observed no apparent correlation between α‐amylase concentrations and Likert scores of the three coping styles. Conclusion These results suggest that salivary cortisol concentrations might reflect the stress‐coping status, particularly involving the problem‐focused coping style.

“…Saliva cortisol is used as a biomarker of stress and intensely psychological stress [9][10][11]. Measurement of salivary cortisol hormone level provides a simple, non-invasive and stress-free measurement [11][12][13][14].…”
